earl doesn't/didn't have poor fundamentals. his follow through has always been straight as a die, it's just that he does it faster than others, which leads people to assume (as with other fast players) that "he rushed it". it's not dissimilar to filler, the connection and follow through.
earl would have thrived on the new 9b tour if he was younger and not mental.
but i agree with basementdweller, that for many of those players it would have been torture. i watched an old one pocket match with strawberry and grady some week ago and it was at the level that had they played buffalos today, they would be out by the third round. not because of pocket size, but because of inferior play. and i love grady, he's an absolute legend who did a lot for one pocket.
